He was so young. Only 16. Anyway, my prediction as to what comes next.
Tails' future: Tails becomes an underage emo pornstar.
Knuckles' future: Knuckles will go back to jacking off. Oh yeah, and protecting the master emerald.
Amy's future: 3 objects. Knife, wrist, Amy. Surely you can fill the gaps.
Eggman's future: Eggman will die of heart disease. But then again, we all knew that was gonna happen.
